I'm going to use the substitution method.
If y = - 3/2 - 7, then:
1/2x + 5 = - 3/2x - 7
Combine like terms:
4/2x = - 12. Mutiply both sides by 2/4 to get x = -12 (2/4)
Simplify to get:
x = - 6.
Plug - 6 back in for x in either equation.
Y = 1/2( - 6) + 5 which becomes Y = - 3 + 5.
X = - 6, Y = 2
It is trueee....... hope this helps
Answer:
it should be 4.24264068712 looked it up
81.56+n-2.55=0
81.56+n=2.55
n=2.55-81.56
n=-79.01
